Endura roof leaks?

[Swanee]

Our 2006 Endura was purchased used with less than 7000 miles on it the price was good, it was beautiful and what we have been looking for. We bought it from Camping World their service was great and continues to be. They stopped the initial leak it took a couple of weeks. Have been through several weeks of rain no leaks. Just got back from a trip to Savannah Ga. poured for two days and we had a leak from the roof in the bathroom and in the cab.
I am just woundering has any other Endura had problems like this, any input would be appreciated.

Thanks
